Introduced in the 1960s, the Persol 714 was a folding adaptation of the famous 649, and was perhaps the first-ever collapsible pair of glasses. Designed for comfort and convenience, the 714 was made famous by Steve McQueen who wore them in the Thomas Crowne Affair and are still among the most popular and fashionable sunglasses today. The tortoise frame features blue, gradient, polarized lenses.
